  • There are many types of audio files, e.g. WAV, MP3, AAC etc. You probably need to be more specific about the file you are trying to decode. Have you googled 'xxx file format' where 'xxx' is the file extension you have? Commented Aug 30, 2020 at 21:12

Here is the specification of the wav format header:

  • Sampling rate in Hertz: bytes 25-28 of header
  • Channels (Mono/Stereo): bytes 23/24 of header
  • PCM: bytes 21-22 of header
  • Bit depth (8/16/24/32/64): bytes 35-36 of header
  • Number of Samples and Duration in seconds: you can deduce it from other data in header.

To inspect this data, you could read the file as a binary stream and then interpret the stream accordingly. This question should guide you.
